srncrrrcn'rro v" forming part of Letters of Massachusetts, haveinvented certain Imiollowing is aspecification.- 1 1 This invention relates to that class of soleproveinents in Nailing-Machines, of whichthe nailing machines inwhich a .continuous wire is fed into the machine andcut up into nails or fastenings, which are pointed 1 at r one end and driven into j the'boot or. shoe asfast as.

formed. An example of. this class of machines to which .my. invention vrelates .is found in Letters Patent to Lamphear, dated August 23, 1859. J 1

The present invention has .for its object to enablea machine of. this class to deal with wire composed of ametallio shell or tube and a core or filling of waxed thread or other fibrous material and convert the same into nails or fastening's, eachpointed at one end.

This invention also has for its object to provide; improved means for regulating the length ofeach feed movement of the wire, so as to regulate the length of the nails, and also to prevent the nail from tipping from a vertical position after it is severed and. formed and while itis being moved forward to position under the driver. g

To these ends my-invention consists in the improvements which I will now proceed todescribe and claim. l

In the drawings, A represents a head. or plate supporting theawl a, and adapted to reciprocate vertically in guides on a supportinghead, B, the latter being adapted to recipro arm or support, 0, Fig. '2. The plateAis reslide, (1, pivoted to a disk or eccentric, c, 011 the driving-shaft f, and working in a slot in tally by the eccentric e, which as it rotates represents the wire from which the fasten ingsare made, saidwire being composed of a tube of metal and a core or filling of waxed thread, the nails or. fastenings formed therefrom embodying the invention described in Letters Patent to Henry S. Onshman, granted May 15, 1877, No. 190,670. Said wire is supported on a reel, hereinaftcr described, and is presented tothe cutting andpointing devices, hereinafter described, by a feed dog or lever, k, which,rin the construction shown in Fig. 1, is pivoted at Z to the vertically-reciprocating plate A, and hasa pointed end engaging with the wire. The opposite end of the lever it pro jects, so as to strike a projection, in, on the ciprocated vertically by. means of aroller or said plate. The head Bis reciprocated horizoncomes in contact with parts of the head B be headqBjvhen the plate A is moved down wardly and projection, m, on' the head B when the plate A is moved upwardly. A

spring," a, secured at one end to the plate A and at theother end to theonter end of the cate horizontally ona dovetail guideon a fixed dog It, holds the pointed end of said dog normally in engagement with the wire, and the contact of the dog with either the projections m or 'mturns' the dog on its pivot, so as to disengage its pointed end from the wire. It will be seen, therefore,- that the dog is engaged with the wire and adapted to feed the same only when its outer end coincides with the space between the projections m m, the spring at being thus enabled to hold: the pointed end of the dog against the wire. The feedingtakes place during the downward movement of the plate A, after the dog 70 leaves the projection m and until it strikes the projection m. When the plate A rises, the dog 70 slips on the wire. In the construction shown in Figs. 12 and 13 the dogk is pivoted to a secondary slide or plate, A, which is adapted to slidevertically on a dovetail guide, A", 011 the plate A, and is provided with an upwardly-projecting"arm, A, having a stud, A, which enters a slot in one end of a bell-crank lever, A pivoted at A to a fixedarm or bracket on the head 0. The

. other arm of the lever A is engaged with a structions the position of the projection m governs the length of the nails.

I make said projection variable in position to vary. the length of the nails by attaching the projection m to a plate, on", which is vertically movable 011 a dovetail guide, m, on the head 13. The plate m has an arm, on", entering a slot in a lever, m,'which is pivoted at m to the fixed supporting-frame, and -is provided with means, hereinafter described,'whereby the operator is enabled to lower the projection m and increase the length of the nails and raise said projection, and thus decrease the length of the nails.

represents a cutter formed by cutting a V- shaped groove in a bar of metal which is'rect angular in cross-section, thereby forming oppositely-inclined cuttingedges 2 2 at the sides of said groove and a horizontal cutting-edge, 3, at the under side of the bar. The cutter 0 is adjustably secured to an oscillatory arm or lever, 12, which is pivoted to thehead B, and is oscillated by means of a projection, g, on the plate A, which depresses said lever when the plate A descends, and a spring, 2', which raises the lever when the plate A rises. The cutter 0 is thus given an cndwise reciprocating movement.

8 represents a fixed cutter or plate attached to the head 13, said cutter being V-shaped in cross-section and adapted to fit closely the groove in the cutter 0, the inclined sides of the plate 8 forming cutting-edges 4 4L, cooperating-- with the edges 2 2 of the cutter 0.

t represents a flat cutter attached to the head B, and having its end sharpened to form a cutting-edge, 5, adapted to co-operate with the edge 3 of the cutter o. The wire passes between the cutter 0 and the cutters s t, and when the cutter 0 moves forward the edges 2 2 and 4 4; co-operate to sever the wire with a V-shaped out, which bevels the end of the wire on two sides, leaving two V-shaped tongues of metal at opposite sides of the wire. These tongues are pressed inwardly by the joint action of a bevel-endedV-shaped block, u,which is fitted into the groove of the cutter ,0 and the correspondingly-beveled end of the cutter s, as shown in Fig. 7, thus, giving the end of the wire four beveled sides. At the same time the cutting-edges 3 and '5 co-operate in severing the wire at a lower point, thus detaching a nail previously pointed at its lower end, as above described, the edges 3 and 5 making a straight cut, which gives the nail a fiat head. The chip or waste piece that is formed between the two cuts slides out through an open space,

8, between the cutters s t. The cutters o and s tare confined in place, respecti vely,by aplate,

a, which is screwed to the lever p, and clamps the cutter 0 against the same, and a plate, I), which is screwed to the head B and clamps the cutters st. Each cutter canbe adjusted lengthwise to compensate for wear, &c., by loosening the clamping-plate a or b. The compressor u is held in place by the compression against it of the sides of the cutter 0 under the clamping pressure of the plate a. The proX- imate surfaces of the head 13 and plate I) are recessed or grooved to fit the cutters s t, as shown in Fig. 5. Each nail, after it is severed from the wire, drops into a channel, (1, in front of a carrier, 0. The carrier is a plate adapted to reciprocate in the channel and force each nail to a point over the orifice in the nose '6, through which the driver passes to drive the nail. The carrier is pivoted to a lever, 11, which is pivoted at a to a car or cars formed on the head B,.and is oscillated'so as to reciprocate the carrier horizontally by a cam, e, on the vertically-sliding plate A, bearing against a roller in the upper end of the lever (1 and a spring, 1'', which holds said roller against the cam, as shown in 'Fig. 2, or by a cam-groove, d, in a plate rigidly attached to the head I), said groove receiving a stud, 0", on the lever (P, as shown in Figs. 12 and 13.

9 represents a laterally movable spring, which normally presses into the channel (1 in front of the part of said channel into which the nail drops from the cutters, and is attached at one endto the carrier. The spring g is slightly hooked at its free end, so that it retains the nail in a vertical position against the end of the carrier while the carrier is pushing thenail 253.228 i p a :i

The'nail is thus kept in avertical-position, so i that it will be properly presented to the driver. The beveled end 9 and surface g are provided with alternating ribs 9 and intermediate grooves, the ribs of the end g fitting in the grooves of the surface g, and viceversa. This tions of the head of another nail, a thin neck of metal being left between the two notches, which neck is afterward broken to i sever the nail below it from the wire; but I am not aware that a wire has ever been cut at two points simultaneously toform the point of one nail and the head of anothen'as above de scribed. i i

The wireis wound upon areel, j, which is provided with a central spool or drum, 6, and a peripheral flange, 7, said drum and flange being separated by an annular space, in which the coil of wire is placed. Said coil is wound so that it will unwind from theinterior of the coil. An annular plate, 9, is detachably secured to the flange 7 and holds the coil in place, said plate being separated. from the spool 6 by an annular slot, 8, through which the wire passes to the machine. The drum is supported in any convenient relation to the machine. The cutter 0 maybe supported on a'slide rcciproeated in a rectilineardirection, instead of being oscillated, as described.

H represents awork-supporting horn, which is pivoted on a vertical rod or standard, H", so that it canrotate in the usual manner under the noser The horn is provided at its upper endwith a horizontal bed, H, which isprovided with a circular groove, H, arranged un der the awl, so as to furnish trough or depressionunder the awl a to receive the point of the awl when the latter entirely penetrates the bottom of a bootor shoe, the awl moving in said troughwhile feeding the work. The

surfaces of the bed H on the either side of the groove H support the surface of the inner sole close to the awl and prevent the latter from raising burrs or protuberances in making its perforations. The groove H is eccentric to the awl, as shown in Figs. 14 and 15, a in Fig. 14 representing the awl in the position which it assumes while penetrating the sole, andc the position of the awl at the end of its feed movement. The arrangement of the groove is such that some portion of it will always sustainthe relation to the awl shown in Fig. 14 in any position to which the horn may be turned. The horn H is swivelcd .on the vertical rod H, which is adapted to slide vertically in gnidesH on the frame of the machine, and is pressed upwardly by a spring, S, interposed between the lower guide, H, and a collar, H, rigidly attached to the rod H The rod H is connected by a link, H, with a treadle, H, pivoted to the frame of the machine at H. From the rear end of the tre'adle H a rod, 1, extends upwardly through an orifice in the frame of the machine, and is provided at its upper end with a roller, 1*, bearing on a-eam, I, on the drivingshaft f, the roller I being pressed downwardly against said cam by the action of the spring S through the intermediate parts. The cam therefore acts to give the horn a slight upward-andsdownward movement when the machine is in operation. The rod 1 is made in two parts, which are connected by a nut, J, pro'videdin one end of its aperture with right-hand screw-threads and at the other end with left-hand screw-threads,

the same engaging with corresponding threads cut in the respective parts of the rod l, so'that by turning thenut J said rod can be lengthened or shortened to diminish or increase the distance between the work-support of the horn H and the nose '5 when the horn is in its nor mal position, thus adapting the horn to dif ferent thicknesses of soles. The operator can,

by depressing the treadle H, depress the horn below its normal position to enable a boot or shoe to be appliedor removed conveniently. The horn supporting and operating devices above described in themselves formno part of my invention, as they are common in other machines of this class. 1

' To the rod I, below the nut J ,is'rigid1y at h Ltachedan arm or bracket, K, having in. its

outer end a vertical orifice, through which passes a vertical rod L, passing alsothrough a guide, L", on the-frame of the machine, and

The

pivoted to the rear end of the lever m rod L is adapted to slide in the arm K and respond with the adjustment of the horn. For example, when the rod 1 is lengthened to bring the work-support of the horn nearer the nose 2', andthus adapt the horn to a thinner sole than before, the bracket K, which is depressed orlowered in. the operation of length- Said spring presses a.

ening the rod I, will depress the rod L and correspondingly raise the projection in through the lever m thereby providing for a shorter nail corresponding to the thickness of the sole, for which the hornis adapted by said adjustment. The length of the nails and the vrtt cal position of the horn are thus siniultane guide L and prevent the upward movement treadle, m whereby the operatoris enabledto purpose of applying or removing a boot or m and projection m.

determines the depression of the projection ously adjusted. The rod L is provided with a fixed collar, 12*, arranged to abut against the of the rod L when the horn is depressed by the operator below its normal position for the shoe.. 7

I do not limit myself to adjusting the projection m simultaneously with the horn, for said adjustment may be effected by independent means, as shown in Fig. 16, in which the lever m is connected by a rod, m with a raise or lower the projection m. Said treadle has a spring, 8, which normally raises the outer end of the treadle. The rod m passes through a perforated arm, n, 011 the supporting-frame, and is provided above and below said arm with adjustable stops or collars Mn, which limit the vertical movements of the rod The stop a is held by the spring 8 against the arm n", and determines the position of the projection m for short nails, while the stop a, which is raised to the arm n by the depression of the treadle,

when longer nails are'required; By adjust-' ing said' stops the length of the shorter and longer nails may be varied. It will be seen that the change in the length of nails can be effected without stopping the operation of the machine. 7 I
